SUPPLEMENTAL SEAT FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 621,722, dated March21, 1899.

* Application filed September 19,1898. Serial No. 691,361. (No model.)

T0 all whom t may concern:

Be it known that I, FRANCIS T. T. STANIER, a citizen of the Dominion ofCanada, residing at Chilliwack, in the Province of British Columbia,Canada, have invented a new and useful Supplemental Seat for Bicycles,of which the following is a specification.

My invention relates to improvements in supplemental seats for bicycles;and it consists of a horizontal support-bar ,passing through the rearframe of the bicycle, to which it is attached, with the inner endresting against the rear part of the frame, into which the saddle-postis introduced, and resting on the cross-tie of the saidframe. Thebackward end of the bar iswidened to support the seat, and this issupported byafleXible stay passed over the saddle-post.

The object of my invention is to provide a seat for a child that is verysimple and cheap and that may be attached to any of the standardpatterns of bicycle frames with little trouble and delay and also thatmay be adj usted to place the seat at the desired pitch for the comfortof the rider. I attain this object by the mechanism or the apparatusillustrated in the accompanying drawings, in which- Figure 1 shows theposition of my invention when in use. Fig. 2 is a plan of the seatdetached. Fig. 3 isan inverted detail plan showing the means forfastening the opposite ends of the tension-wire. Fig. 4 shows a sideelevation of the same and Fig. 5 is a cross-section of theclamping-plate, taken on the line 1 1 in Fig. 2.

Similar letters and nu'merals refer to similar parts throughout theseveral views.

The longitudinal bar 10 is preferably made of wood, and it is formed topass between the forks of the rear part of the frame, as a, and rest onthe cross-tie b, which forms afulcrum, and its inner end is providedwith a flute 10a, which snugly fits and rests against the frame c. Theprojecting end of the bar 10 is widened and formed to support aseat 11.This, however, may be modified and made to suit the requirements of thedemand. Secured .to and beneath the bar 10, approximately at its pointof enlargement for the seat, is a wedgeshaped plate 12, and lyingagainst this plate 12 is a similar one, 13, the same being held drawnfrom between the plates 12 and 13 by the weight of the rider, Iprovidetheir facing surfaces with corrugations 16, these flutes being placed atright angles to the ends of the wires 15,so that as the plates areforced toward each other by the bolt 14 the said ends of the wire willbe securely gripped by the ribs of the corrugationsA As the rear forksof the frames in bicycles are not all placed the same distance apart itIis obvious that the bar 10 in some instances will not fit and lie closeto such forks. Therei fore to provide against any lateral movement ofthe bar I provide a slidable plate 17. (See Figs. 2 and 5.) The saidplate 17 is secured to the bar 10 by a bolt 18 passing through alongitudinal slot therein and through a slot 17fL in the said plate.When the bar 10 is placed between the forks o, the plate 17 is pressedtight against the same and secured with its wide end on the inner sideof the forks, so that the bar 10 cannot work backward.

To prevent the edges of the plate 17 from making contact with andabrading the forks and from having lateral movement, the edges areturned down, as at 17h, and thus present iiatsurfaces to the said forksinstead of narrow edges.

From the foregoing it'is shown that my seat may be universally adopted,and it may be attached and detached to and from abicycle in a very shortspace of time, it being simply necessary to drop the loop over thesaddle and let it rest on the post d and adjust the plate 17 to preventthe bar 10 from having any lateral movement.

Having now described my invention, what I claim, and desire to secure byLetters Pat ent, is;

roo

l. Asupplenlental seat for a bicycle,oo1npris ing a bar l0 arranged tolie on the cross-tie I) of the frame and with its fluted end restingagainst the frame c, and an adjustable tension- Support l5 securedbeneath the seat on the projecting end of the said bar and lying overthe saddle-post d, as specified.

2. A bar l0 having a fluted end to lie against the upward rear projectin g frame cof abicycle, the said bar to pass between the rear framesof same, a wedge-shaped clamping-plate 17 on the upper side of said bar,and a bolt passing through a longitudinal slot in the bar and a slot inthe said plate7 whereby the plate may be secured to connect with theopposite forks a of the frame, and means forsupporting the projectingend of the bar on which is arranged a seat, as specied.
